Module interface:

• 1-Channel relay module， with photoelectric isolation
• The module can be high or low by a jumper setting trigger
• With power and relay action indicator
• The module Operating voltage 5V
• The module uses genuine quality relay， normally open interfaces Maximum load: AC 250V/10A， DC 30V/10A
  • DC+: positive power supply (VCC)(5V)
  • DC-: negative power supply (GND)
  • IN: The control end， the driving current should be more than 4mA
  • COM: The control of loop of earth wire

           Program :

• int RelayPin = 6;

   

  void setup()

  {

       pinMode(RelayPin，OUTPUT);

  }

   

  void loop()

  {

       char i;

       i = analogRead(5);

       if(i > 5)

       {

            digitalWrite(RelayPin，HIGH);

       }

       else

       {

            digitalWrite(RelayPin，LOW);

       }
